Effect of iron fortification on body iron in anemic Vietnamese women.

Body iron was calculated from the ratio of serum transferrin receptor to serum ferritin. Positive values (clear area) depict storage iron, and negative values (shaded area) indicate tissue iron deficiency. Data are shown for 15 women given no additional iron (control) and 15 women given a meal fortified with 10 mg iron as NaFeEDTA 6 days each week (fortified). Vertical bars represent ± 1 SEM.
